I first had this in New Zealand, and recreated at home in London as a) it’s not that easy to get non-bank breaking, half decent quality sushi in this town b) hardly anyone does chicken sushi, usually sticking to too-old tuna.
Works well with teriyaki chicken or, a huge cheat, in this case, I used southern fried chicken breast strips from Tesco….
It may be far from authentic but the combination of the chicken, sushi rice, and accompanying wasabi, and ginger is about as yummy as possibly for healthy foods.
For the adventurous, tempura sushi could be attempted, I’ve seen it advertised in Beijing but never quite made it…. sounds decadent.
